However, the prior art still has structural deficiencies, in that the connection cover is detachably assembled on the lower opening, the position limit is unreliable, and there is a risk that the connection cover will be washed off when filtering high-pressure coffee liquid.

[0004] Therefore, there is still room for improvement and development in the existing technology. Utility Model Content

[0005] In view of the problems of the prior art, the utility model provides a funnel assembly and a coffee machine with reliable limiting function, which can prevent the funnel support from being washed away when filtering high-pressure coffee liquid and is safer to use.

[0006] In order to achieve the above purpose, the technical solution applied by the utility model is as follows:

[0007] A funnel assembly includes a funnel seat, a funnel bracket and a filter cup; a through cavity is formed in the funnel seat, and an upper opening and a lower opening connected to the through cavity are provided on the funnel seat; the funnel bracket and the filter cup can be removed and installed in the through cavity separately or simultaneously; when the filter cup is separately provided in the through cavity, the filter cup is provided in the middle and upper part of the through cavity; when the funnel bracket is separately provided in the through cavity, the funnel bracket is provided in the middle and lower part of the through cavity, and the upper end of the funnel bracket is limited to be located in the through cavity, and the lower end of the funnel bracket extends out of the lower opening and is fixedly connected with a coffee spout; when the funnel bracket and the filter cup are simultaneously provided in the through cavity, the filter cup and the funnel bracket are provided in the through cavity with upper and lower intervals. In this way, the funnel bracket and the filter cup can be removed and installed in the through cavity separately or simultaneously, so as to realize the switching of different functions of the funnel assembly; it should be noted that when the funnel bracket is provided in the through cavity, the upper end of the funnel bracket is limited to be located in the through cavity, and the funnel bracket will not be washed out when filtering high-pressure coffee liquid, so that it is safer to use.

[0008] In actual application, when assembling the funnel bracket and the filter cup, the funnel bracket is first installed in the through cavity through the upper opening, and then the filter cup is installed. When the funnel bracket needs to be removed, the filter cup is first removed, and then the funnel bracket is removed from the upper opening.

[0009] According to the above scheme, a first locking component is provided between the funnel support and the through cavity, and a second locking component is provided between the filter cup and the through cavity.

[0010] According to the above solution, the first locking assembly includes a first limiting step provided on the outer wall of the funnel bracket and a second limiting step provided on the inner wall of the through cavity. After the funnel bracket is assembled, the first limiting step and the second limiting step are engaged with each other up and down. With this arrangement, after the funnel bracket is assembled, the limiting is reliable, and the funnel bracket will not be washed off when filtering high-pressure coffee liquid.

[0011] According to the above solution, the second limiting step is located on the inner wall of the lower opening, and the funnel bracket can close the lower opening after being assembled. This arrangement prevents the coffee liquid from leaking out.

[0017] According to the above solution, a positioning groove for fixing the clamping spring is provided on the inner wall of the through cavity, and a conical portion is provided at the lower part of the filter cup. In this way, when the filter cup is assembled, the compression clamping spring can be squeezed open by the conical portion, and when the truncated cone portion corresponds to the clamping spring, the clamping spring can clamp the truncated cone portion.

[0018] In practical applications, in an initial state, the outer diameter of the truncated cone portion is larger than the inner diameter of the retaining spring, and the outer diameter of the conical portion is smaller than the inner diameter of the retaining spring.

[0019] According to the above solution, the opening of the filter cup is formed with a flange, and after the filter cup is assembled, the flange cooperates with the upper opening of the funnel seat to lock. In this way, after the filter cup is assembled, the flange is hung on the upper opening of the funnel seat to achieve position limiting.

[0020] According to the above scheme, the lower end of the funnel bracket is fixedly connected to the coffee spout through a fixing nut, a guide hole is provided in the fixing nut to connect the through cavity with the coffee spout, and a liquid outlet is provided on the coffee spout. In this way, the coffee spout is fixed to the lower end of the funnel bracket through the fixing nut, which is convenient for loading and unloading, and the guide hole is provided in the fixing nut to connect the through cavity with the coffee spout, which is convenient for guiding the coffee liquid in the through cavity to the coffee spout for discharge.

[0021] In practical applications, the coffee spout includes liquid outlet 1 or includes liquid outlet 1 and liquid outlet 2 that are symmetrically arranged.

[0022] According to the above solution, a handle is also included, wherein the handle is provided with a stud, and the funnel seat is provided with a nut seat, and the stud is fixedly connected with the nut seat through a thread.
